402. The maintenance program must be drawn up and signed by one or more members of a professional order according to their field of practice and whose activities are related to the field of water cooling tower facilities. The program must contain

(1)  the procedure for winterizing and re-starting, if applicable;

(2)  the procedure for stopping and re-starting during the operation period;

(3)  the cleaning procedure;

(4)  the procedure for maintaining the quality of the water in order to minimize the development of bacteria and to permanently limit the Legionella pneumophila concentration to a level below 10,000 CFU/L (colony-forming units per litre of water). That procedure must include

(a)  the place where the samples must be taken for the analysis of the Legionella pneumophila concentration in the water; and

(b)  the corrective measures to be applied when the result of a sample analysis indicates a Legionella pneumophila concentration equal to or greater than 10,000 CFU/L but less than 1,000,000 CFU/L, in order to bring the Legionella pneumophila concentration to a level below 10,000 CFU/L;

(5)  the decontamination procedure to be applied when the result of a sample analysis indicates a Legionella pneumophila concentration of 1,000,000 CFU/L or more;

(6)  the measures for reducing corrosion, scaling and the accumulation of organic matter;

(7)  a schematic plan of the water network of the water cooling tower facility;

(8)  the list of the chemical products and substances to be used and their description, if applicable; and

(9)  the measures for verifying the mechanical components of the water cooling tower facility.

The maintenance program must be drawn up by taking into account the documents indicated in Schedule III.
